SYNOPSIS

tempo [options] [filename]


options:
  -c          Do all requested iterations, even if apparently converged
  -d<path>    Path to 'tempo.cfg', default: environment variable 'TEMPO'
  -f<par>     Over-rides the default parameter file name with <par>
  -g[O]       GRO mode; 'O' is single-letter observatory code
  -h          Help message
  -j          Output JUMP values in xxx.par file
  -l<xx>      Max number of parameters to be fit (guides memory allocation)
  -m<xx>      Max number of TOAs to be fit (guides memory allocation)
  -no<file>   Write out absolute pulse numbers to file
  -ni<file>   Get absolute pulse numbers from file
  -o          'Old-style' parameters at head of <fname>
  -p          Parameters corrected for pulsar space motion
  -r          Save the partial-derivatives file, resid1.tmp 
  -v          Print out version number
  -x          Make an export file in ITOA format
  -z	      Compute polonomial coefficients for predictions 



ENVIRONMENT

The 'TEMPO' environment variable is normally set to the name of the
directory containing the 'tempo.cfg' configuration file. The -d option
overrides the environment variable.

OPTIONS

-c 
   do all requested iterations (NITER), even if apparently converged
   (possibly useful when exploring unusually-shaped chi^2 space)

-d <path> 
   override environment variable 'TEMPO' with <path>. Path may be '.'. 

-f <par>
   override default name for free-format input parameter file (see INPUT
   FILES below).

-g[O] 
   Write post-fit parameters to file 'gro.1' (and, for binaries, gro.2)
   in the format used for interchange with Gamma Ray Observatory 
   investigators.  Single-letter observatory code, O, is optional;  default 
   is P (for Princeton). If PEPOCH is not at the centre of the data span,
   adjusted parameters are written to gro.99.

-h
   Print help message

-j
   Write offset values ("JUMP_1", etc.) to parameter file.

-l <xxx>
-m <yyy>
   Expected maximum number of parameters (xxx) and TOAs (yyy) in the fit.  
   (Default values are hard-wired in source file dim.h.)  
   These values are used to allocate memory.  If either is too small,
   memory will be re-allocated, requiring an extra read through the
   TOA file.   

-ni <file>
   Read pulse numbers from file.  These values override the pulse numbers
   normally calculated internally to tempo.

-no <file>
   Write pulse numbers to file.  Main purpose is to produce input for '-ni'
   option.        

-o selects 'fixed-format header' input file.  See INPUT FILE below.

-p calculate pulsar parameters compensating for effects of pulsar space
   velocity.

-r write pre-fit residuals and their derivatives with respect
   to each parameter to file 'resid1.tmp'

-v report version number

-x write TOAs in interchange time of arrival (ITOA) format to file 'itoa.out'

-z run prediction mode, in which predicted pulsar ephemerides are written
   to file polyco.dat (see PREDICTION MODE). If given, <fname> overrides
   'tz.in' for the file listing default prediction parameters and source list.
